For parents and educators
Friends often throw it around as a joke while roasting each other. Aimed again and again at one kid, it's put-down language and can be part of bullying.
If you’re worried
Ask who says it and how it feels when it's aimed at them. If it's constant or a group is ganging up, save screenshots and talk to the school. Kids Help Phone is there for your child: 1-800-668-6868 or text 686868.
Where it came from
Old slang that blew up on TikTok and in group chats in 2025.
